APOLLO BIO PRO ADJ. STRAP FINS

[DiverQueen]

So often fin fit is based on how the foot pocket fits to the booties or drysuit boots the diver wears.  Not so much emphasis is given to the blade material and flex to function dynamics.  The "Nature's Wing" design was created to reduce fatigue to the leg muscles of the recreational diver.  But it's not the best fin choice for someone who needs speed and "traction" in the water.  For that a stiffer carbon fiber or rigid plastic polymer is required.   Other fin designs such as the Mares Plana Quattro utilize a four channel design to allow a specific amount of flex, while still maintaining the propulsion capability of the water in the center of the flexed zone.

For my first open water dives, I used an older pair of Sea Quest Kevlar blades.  I got muscle cramps due to their rigidity and my being out of shape for the shape I was in!!  The second day I used standard rubber full foot fins and aside from the fact that I could chillingly feel the thermocline, I had no cramps because they were a more flexible and forgiving material.

If the shop gives you the option,  "try it before you buy it!" 

Try to rent a variety of fins before you settle on what you think might work best. 

Check the "ScubaLab" test results for various aspects of fin design and function. 

Ask your fellow divers what they like about the fins they dive with.
